Specimen Products Rendition 26 Tube Amp – Inspired by the original of all time, an amp few have actually seen—Leo Fender's Model 26. The Specimen Rendition 26 features a Jensen Alnico 8" speaker. It struggles along perfectly, recreating the tones of the old favorite that launched an empire. The Rendition 26 is simple—a cabinet made of solid walnut, a chassis wired point-to- point. A design as straightforward and sincere as its influence.
